We run 2 cranks on a "3 way". 24" is the 1st (sometimes larger) crank then 36" is the second. The frist 1 seems to set the depth & the second 1 just runs.
A little hard maybe to start with but it does work.
WE HAVE EVEN CAUGHT " DOUBLES"
Popular on Lake St. Clair & we use it once in a while on Lake Erie!!!
